RECESSIONAL ICE BORDERS IN BERKSHIRE, MASS. 347 



Fig. 8. — This map shows the distribution of morainic and border drainage feat- 

 ures without any interpolation. When drawn upon the topographic contour maps, 

 their relations to topography are brought out, and their distribution and arrangement 

 are more intelligible. All moraine fragments which seemed uncertain in their rela- 

 tions to the ice-front are represented on the map as lateral.
